DE S. SABINO, PAULO HENRIQUE et al. Effects of insecticides on CO 2 release by entomopathogenic nematodes (Nematoda: Rhabditida) and development of their mutualistic bacteria. Rev. Colomb. Entomol. [online]. 2017, vol.43, n.1, pp.38-40. ISSN 0120-0488.

The present study aimed to evaluate the CO2 release by infective juveniles (IJs) and the viability of mutualistic bacteria of entomopathogenic nematodes (EPNs) when exposed to synthetic insecticides. Two species of EPNs, Heteror- habditis amazonensis JPM4 and Steinernema carpocapsae All, were tested. The applied insecticides were Vertimec® (aba- mectin) and Klorpan® (chlorpyrifos). Gas chromatography was employed for CO2 analysis. The bacteria were isolated and the colony development was evaluated in sterile Petri dishes. Vertimec® triggered greater CO2 release by the nematodes, associated with changes in their metabolic activity, than Klorpan®. Vertimec® and Klorpan® did not inhibit the bacterial development.
